Seems my LSJ narrowband O2 sensor is acting funny compared to my truck. At highway speeds it doesnt switch right at all. I will attach a screenshot of this. It only seems to do this at highway speeds.

From the picture it looks like its going "up and down" like normal to me atleast.
The front o2 sensor will always go to lean to rich as its trying to achive stoich during normal driving.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
